They were an attractive, seemingly normal couple, full of smiles in photos taken at their 1991 wedding in the Ontario town of Niagara-on-the-Lake. That happy façade made it all the harder for Canadians to accept the brutal crimes committed by Paul Bernardo and Karla Homolka.

Bernardo was convicted in 1995 of the kidnapping, raping and murdering of southern Ontario teenagers Kristen French and Leslie Mahaffy. Homolka portrayed herself as the innocent victim of a murderous monster. She struck a deal with prosecutors (later dubbed the "deal with the devil") and pleaded guilty to manslaughter in the deaths in exchange for a 12-year prison sentence.

But videotapes of the crimes, found after the plea bargain, showed her to be a more active participant. Public outrage about Homolka's sentence had barely cooled by the time of her extremely high-profile release from prison in 2005.
